. PORTABLE METALLIG SMOKE-HOUSE. 1 7

LYMAN S. STEVENS, OF WALTHAM, MASSACHUSETTS. Letters Patent ZV o. 59,931, dated November 20, 1866.

, SPECIFICATION- TO ALL WHOM IT MAY CONCERN:

Be it known that I, LYMAN S. STEVENS, of Valtham, in the county of Middlesex, and Stateof LIaSsachTr; setts, have invented a new and useful Portable Metallic SmokeHouse; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being .had to the accompanying drawing forming a part of this specification, in which Figure 1 is an elevation, and

Figure 2 a plan of the fire box F.

Like letters indicate like parts in both figures.

v This invention consists of a new article of manufacture, a portable metallic smoke-house. Others skilled in the, art may make and use my invention by following the directions and drawings of this specification.

a metallic cylinder closed at each end by disks, B B, which are made with flanges, C C, at right angles with their disks, so as to tightly close the cylinderv at each end. Rods of metal pass through these disks and tightly press them to the ends of the cylinder, being fastened by nuts or other'devices at each end of the rods. Across the top of the cylinder, and near the upper disk, Z2, are rods (1, carrying hooks, e, to hang the meat upon, .A. box, F, about one fifth of the height of the cylinder, is inserted near the bottom for a fire box, and above it is a mica plate, m, for observing the condition of the fire. Flanges on this box close the opening into the cylinder through which the fire box is inserted, or there may be a close-fitting door through which to insert either pans or boxes, hereafter described. Holes, h, are pierced on the side ofthe cylinder at some point above the sides of the fire box, and are each furnished with a slide, 8,01 cover, to allow the admission of air to be regulated so that combustion shall always :be very imperfect. A swinging door, near the top of the cylinder allows the cylinder to be opened to place the meat to be operated upon within. A. smoke-house of this construction, about six feet in height and three feet .in diameter, will cure at one time about one hundred pounds of meat in the usual pieces, but these proportions may be varied according to the quantity to be smoked at one time. The fire box, f, 1 nay, if desired, be replaced by one or more loose pans for containing fuel their sides in no instance rising so high as the air-holes in the side of the cylinder, that combustion may always be imperfect and in the larger smoke -hcuse of this construction the upperdoor, 9, may be dispensed with, and the smoke-house entered to hang upmeat to be cured, by means of the fire-box opening. All joints should fit tightly.

What I claim as my invention, and desire to secure by Letters Patent, is- As a new article of manufacture, a portable metallic smoke-house, substantially as describec' LYMAN S. STEVENS. Witnesses:
